Just repalced 6 plugs.

I just replaced 6 plugs on my 97E320 w/ 104 engine. I replaced the plugs w/ original Bosch plugs. A day after I replaced them, the car would occassional run rough, especially when cold. Upon acceleration, the car runs fine. what should I do? Do I replace the spark plug connectors? One more note, this rough idle was never there prior to the plugs being replaced.
